Idk about that... Emailed for a quote to flash the correct BIOS back to my GTX 1080ti and got a response of $295-$495. Literally just a BIOS flash and bro is asking significantly more than the card is worth. Imagine how much he charges for a cracked PCB. Probably at least $2000 USD. Email: "Estimated cost for repair for this device is $295 - $495. If we can’t fix it then the cost is $75 for diagnostics and repair attempts. Current turnaround time for regular service is 4-8 weeks and for expedited service ($95 fee) is 1-9 days."

[@juice7661]

@@Th3Fly1ngCow I have the original bios saved and it can be found online as well. The only problem is the card is not being recognized anymore after flashing the different bios. Several systems I tried refuse to boot entirely with the GPU on any PCIE slot regardless of whether you use a different GPU or even integrated graphics. Only managed to boot in an old haswell era oem system but nvflash wont find any nvidia display adapters. The card basiclly needs to be flashed back manually with an EEPROM reader. Will have to do that myself. Its not my first rodeo with flashes gone bad, but usually you're able to flash back to the original saved bios no problem by just booting with integrated graphics and such...

Backplate adds structure and avoids flex of the pcb, something nvidia card manufacturers could learn. But then again its probably part of their built in obsolescence schemes.

@@waldolemmer I think the magic number is 255. ;)

[@jtnachos16]

@@waldolemmer the board on a GPU is more densely weighted, what with the MASSIVE heatsink that is typically both BIGGER and HEAVIER than the board, which has to stay in constant pressure across all kinds of contact points all over the board, and also has less tolerance for screws touching things due to that increased density of surface components. It's also typically mounted horizontally, with the weight hanging DOWN off the board, as opposed to a motherboard, which is typically either vertical, and thus with less pressure against the mounting points, or on the bottom of the case.

[@waldolemmer]

@@jtnachos16 Ah, it makes sense now, thanks

[@justinbrown691]

@@waldolemmer If you are adding the backplate for rigidity then the more screws the better. The distance of possible deviation is reduced by the addition of each screw. A flexible material attached to a hard material will tend to deform around where it is connected to the ridged material. If the distance between connections is too great the deformations can link up and isolate the connectors causing a kind of dimple (At least in metals). More screws also add redundancy in a part that will see thermal changes and vibration. Honestly, these cards are built to run until they die. Opening a card up should maybe happen once in its life and cheeping out screws would be far more insulting to me personally.

[@Varmint260]

Very satisfying to see you make repairs at such a small scale! Really relaxing to watch. My first experience with a Powercolor card was my 5700XT.

Oooh. New preheater setup? Can you share more on this?

[@W77W]

Heating the leads while bending is NOT helping. The epoxy package loses almost all of its strength at high temperature. At 9:51 you broke the epoxy package around the leg, snapping the tiny bondwire between the leg and the silicon. Bend them at room temperature and support the plastic. I recommend the big flat surfaces of ceramic tweezers to firmly squeeze the package top and bottom, thumb and forefinger directly over the chip. Then a second pair of ordinary tweezers to rotate the leg back to normal. You might prefer a vise for filming but ceramic tweezers are easier. Healthy skepticism should motivate you to grab a plastic packaged IC and start bending legs cold, see how it takes 3-4 bends to fatigue the copper? And when it snaps, there's still a copper nub on the package you can microsolder to. The plastic's reversible brittleness can be observed if you pick a big chip, either a MOSFET or the LQFPs on motherboards, use hot air and a pair of pliers to split/crumble the package and remove the silicon die. I anticipate comments that you're softening the copper. Technically yeah, the metal gets softer, but the ratio between the epoxy strength and copper strength gets worse the hotter you go. The limited annealing that's possible without wrecking the silicon was already achieved by desoldering, trying to forge the copper isn't necessary.

[@northwestrepair]

Makes sense.

Interesting how this component got damaged in the area it's in. As far as that unnecessary resistor goes, I've always heard that boards from Sapphire Nitro/Toxic, ASRock Taichi, and Powercolor Red Devil were heavily over engineered to be almost on par with professional level graphics cards In terms of quality. And that's why you pay a hefty premium for those cards but I will tell you one thing about them, those are cards I have seen being used for not just gaming purposes, but I have seen people use those exact lineups for professional grade work and they don't skimp on the quality. You could of course go out and buy a Radeon Pro, but those lineups basically are pretty much almost equivalent in quality to the stuff you'll pay about two to three times more for. And the only thing they lack is that extra float point precision that you get on the Radeon Pro cards.

Brilliant video, I need to learn how to repair graphics cards.

[@randallsmith4685]

Did you happen to measure the thermal pads?

[@Golecom2]

I don't think the backplate is for cooling. My guess is that it keeps the board firmly attached to the cooling solution, and since is so big and heavy it needs something harder than the pcb. Also with the heat and the weight the pcb may bent.

[@hardrout17]

Good job, Nice skill! I love the semingly total randomness of the repair! How this happened behind the backplate!?
